Snap rings for Tubes Erosion Shields

Snap rings are used in conjunction with Boiler Tubes Erosion Shields, which is a clip that easily installs Boiler Tubes Erosion Shields to the tube.

The snap ring and Boiler Tubes Erosion Shields are overlapped and welded, generally about 190-200 degrees Erosion Shields is a 180-degree semicircle), but also leave a welding position for easy welding and fixing. Generally, each piece of Boiler Tubes Erosion Shields needs to be equipped with 2-4 snap rings with a pitch of 200-500mm.

The anti-wear snap ring is also called clamp, buckle, tube clamp, etc.

The main role of the anti-wear tile snap ring: the role of fixing the anti-wear tile to avoid problems such as the anti-wear tile falling off during installation.

The types of common anti-wear tile rings can be divided into: U-shaped lap type snap ring, butt-type semicircular snap ring.

Install erosion shields with snap ring

The snap ring is a short section that is installed on the pipe in conjunction with the wear-resistant tile. Generally, it is welded to the wear-resistant tile by lap welding, that is, to cover the wear-resistant tile slightly, so it is larger than the wear-resistant tile. The opening arc is Around 190-200 degrees, the welding position needs to be set aside to facilitate welding and fixing. The width of the snap ring must not be less than 20mm.

The installation requirements of anti-friction tiles of different shapes are slightly different. Basically, each anti-friction tile is installed with not less than 2-4 snap rings. The snap ring and the anti-friction tile are welded together to prevent expansion due to heat. The tiles fall off, and the joints are required to be fully welded.

U-shaped snap ring

The inner diameter of the U-shaped snap ring is the outer diameter of the wear-resistant tile plus the thickness of the wear-resistant tile, and the length varies from 20mm to 70mm. It will be 5mm more in semicircle. The extra part during installation will hold the wear-resistant tile and then spot weld. Compared with the butt-type semicircular snap ring, it is stronger after holding the wear-resistant tile and welding.

C-shaped snap ring

C-shaped snap ring is the most common snap ring. Mainly based on the size of anti-friction tile, the diameter and thickness are similar to the matching anti-friction tile, and the length varies from 20mm to 70mm. It is mainly connected to the wear-resistant tile by spot welding when installing the wear-resistant tile, so as to fix and prevent the wear-resistant tile from falling off.

Boiler Tubes Erosion Shields

Boiler Tubes Erosion Shields, also known as anti-corrosion Shields, anti-wear plate, anti-wear protection Shields, anti-wear cover plate, anti-corrosion cover plate, boiler climbing pipe, anti-wear pressure plate, etc. , which are used in combination with snap rings. Processing thickness of Boiler Tubes Erosion Shields Boiler Tubes Erosion Shields are processed in thicknesses of 2mm, 3mm, 4mm, and 5mm. Different thickness is adopted according to the wear severity and the need of heat conduction. Boiler Tubes Erosion Shields are produced using a high-pressure press and professional mold pressing. The production time is short, the welding performance is good, the welding should not fall off, the surface is smooth, and the appearance is beautiful. Boiler Tubes Erosion Shields with bends are formed by pressing on a press or bending with a special abrasive on a tube bender.

Application of Tubes Erosion Shields

Tubes Erosion Shields are mainly used on the windward side of the heating surface of the boiler, such as superheaters, reheaters, economizers, and water-cooled wall pipes. The main role is to protect the heating surface of the boiler pipes, reduce pipeline wear, and increase the heating surface of the pipes. Service life. In general, most of them are called "wear-resistant tile" and "wear-resistant cover plate". Erosion Shields are special boiler accessories. Generally, most of them are used in power station boilers, small boilers are used less, and some coal chemical industries will also use them. Erosion shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life. We offer shielding for tubing, covering straight, bent and finned sections, as well as the clips that hold these in place. In the long term, these shields more than pay for themselves, preventing the costly replacement o...
